摘要: A method for forming a dielectric film having a desired composition comprising sputtering a dielectric material onto a substrate to produce an intermediary film, the intermediary film incorporating one or more elements in addition to those elements included in the desired composition of the dielectric film; and removing the one or more additional elements from the intermediary film to produce the dielectric film having the desired composition.
